1. The problem statement, all variables and given/known data Would anyone be able to tell me if I'm on the right track with determining the peaks on these NMR spectrums? We had to synthesize a product of Chalcone and then hydrogenate it to obtain an unknown product that we have to correctly identify. This had been quite a difficult spectrum for me to interpret and any input would be appreciated! For the IR spectrums, I think I have the right peaks determined and noticed that the carbonyl shift was at 1660 cm-1 on the Chalcone IR and then switched to a higher energy level in the hydrogenated spectrum at 1675 cm-1 from the chalcone spectrum. Is this due to resonance? 2. Relevant equations N/A 3. The attempt at a solution Listed on spectrum.
